Hi everyone, I'm working on a project that makes use of the StAX API and an issue I have encountered is that when wrapping an `XMLStreamReader` with a `StreamFilter`, errors encountered in the setup are not thrown to the caller. The source of the error could be any stream error that is triggered as the `XMLStreamFilterImpl` advances to the next acceptable event. Ultimately, when attempting to utilize the filtered reader, some secondary exception will occur, but the original `Exception` is lost.
I have not seen any other issues related specifically to this problem, so I would like to propose removal of the try/catch in the constructor of `com.sun.org.apache.xerces.internal.impl.XMLStreamFilterImpl` and the method signature changed to declare that `XMLStreamException` is thrown. The constructor is used by `com.sun.xml.internal.stream.XMLInputFactoryImpl.createFilteredReader(XMLStreamReader, StreamFilter)` which itself already declares the same exception and is an implementation of the public `XMLInputFactory` interface. Further, the `nextTag` method of the same class has a bug where it checks for `START_ELEMENT` events twice. I have an OCA in place and I am happy to submit a PR, but I believe that a bug record needs to be opened in order to proceed. Thank you, Mike
